The aim of this study was to assess the growth response of Sesuvium portulacastrum (L.) (a halophyte)
to various NaCl concentrations and hence determine how it is adapted to grow optimally under saline
conditions. S. ...

Residual long-term effects of increased UV-B radiation were investigated in an indigenous plant
species, Dimorphotheca sinuata, by analysing photosynthetic gene expression. Reductions were
observed in the amount of the ...

Bark of Bauhinia purpurea tree was collected and both the water and methanol extracts were prepared. Both extracts were tested for free radical scavenging activities and phenol content. Water extract was then tested for ...

Harpagophytum is bitypic and native to Southern Africa. Its two species are Harpagophytum
procumbens and H. zeyheri. H. procumbens is medicinal. A reliable method of identifying the species is through its fruit. However, ...

The influence of burning on soil microbial dehydrogenase activity, nitrogen content and fungal population along the Boro route in the Okavango Delta was assessed in the flood and dry seasons. Soil samples from the burnt ...

Halophilic bacteria from the Makgadikgadi salt pans in north central Botswana were isolated using culture-dependent methods. Polymerase chain reaction (PCR) amplification of the 16S rRNA gene and phylogenetic analysis were ...

The sale of herbal medicine, either as concoctions or single plant specimens, has become common in the streets and main shopping centres of major towns and cities in Botswana. A study was undertaken to collect information ...

Most work globally on Phragmites spp. has been done in temperate northern hemisphere localities, where winter low temperatures and short day lengths cause a seasonal decrease in growth. In this study, we report above-ground ...

The genus Prosopis comprises 44 species. Extensive introgression and hybridization is suspected in the genus, which makes identification of the species very difficult. Accurate identification of the species is crucial in ...

The effects of water stress on the photosynthetic characteristics of two locally-cultivated sorghum cultivars (‘Segaolane’ and ‘Town’) were investigated over a period of weeks. Water stress was imposed on 1-week-old plants ...

Biltong is a dried ready to eat meat product that is produced and consumed to a large extent in
Botswana. A study was undertaken with the objective of determining the microbial quality and
isolating and identifying the ...
